EXECUTIVE SUMMARY

Manang Trade Link (P.) Limited (MTL), a company setup to develop Lower Modi Khola Hydroelectric Project (LMKHEP) has prepared this progress report. Hydro Solutions Group, KL Dugar Group, Murarka Group, Debenara Group, and Mr.Bhujung Gurung as individual partner promoting this project.

The LMKHEP was identified by MTL as a potential hydropower project in the Western Region of Nepal between longitude 83º44’43” and 83º42’30” and latitudes 28º16’18” and 28º14’08” and”. The altitude of the project area varies between 869 m and 767 m above mean sea level (masl).

OBJECTIVE OF THE DOCUMENTS

The objective of this progress report is to present the progresses to date.

1. PROJECT STATUS

The following sub-sections briefly describe the status of the project till date.

1.1 FEASIBILITY STUDY

The feasibility study of the project was undertaken by WRC and reviewed by Hydro

Solutions Private Limited and BPC. GoN has approved the EIA report of the project.

1.2 PPA AND INTERCONNECTION

PPA was signed with NEA on Bhadra 2068. The agreed contract energy is 117.14 GWh

after deducting 4% outage and loss. The connection agreement was signed on

2066/10/14.

1.3 LAND ACQUISITION

Land required for the construction activities has been completed. Approximately 107

ropanies of land (8.5 ropanies of the land at Powerhouse, 69.5 ropanies at Headworks,

12 ropanies for mucking disposal and 15 ropanies at Housing area) has been purchased.

Figures 1, 2, 3 and 4 below show the purchased land for powerhouse, housing and

headwork areas. Similarly 34 ropanies of land has been leased for safe muck disposal

and construction facilities.

1.4 ENGINEERING AND DETAIL DESIGN

Hydro Solutions Engineering & Consultancy Private Limited has undertaken the detail

engineering design of the project. The consultant has created a team of engineers and

geologist for providing design and construction management services for the project. All

the required investigations for underground and surface works have been completed.

Till date the consultant has already submitted the Detailed Project Report (DPR), tender

documents for civil construction and hydro-mechanical fabrication and construction

drawing of Headworks and underground works. MTL has also engaged Australian based

Indian consultant, Entura Hydro Tasmania to check and verify the design of LMKHEP.

The monitoring of the construction works at site by the Consultant is being done

through regular site visits. Other experts have also been engaged to provide specialized

services to enable to foresee and deal with potential problems that can impact work

progress.

2. CIVIL CONSTRUCTION

MTL has appointed two contractors for the execution of civil works of the project. South

Asian Infrastructure Pvt Ltd will be constructing the underground works and Ashish-

Fewa-Nayabato JV will be constructing the surface civil works of the project. MTL has

signed the contract agreement with both of these contractors who have mobilized their

sites and started their works.

2.1 PRE-CONSTRUCTION FACILITIES

All the pre-construction facilities including construction power, water supply, labour

camp, and crusher and batching plant, bunker has been completed at all working sites.

2.2 ACCESS ROADS

Unlike many other hydro projects, this project is easily accessible as all the structures of

the project are along the Pokhara-Baglung highway. The access road to be constructed is

limited to few kilometers, most of which has been successfully constructed.

Constructions of access road to Adit-1, Adit-2, Headworks site, and inlet portal, site

camp and outlet portal have been completed and access road up to penstock area and

surge tank area is being planned to commence soon.

2.3 ADIT TUNNELS

There are two adit tunnels namely Adit-1 and Adit-2 being excavated. The excavation of

two Adits each of length 181 meter and 122 meter has been completed.

2.4 SURFACE STRUCTURES

The concreting works of Undersluice, divide wall, counterfort wall, intake, bed load

deflector and gravel trap and approach canal is going on. Similarly excavation of settling

basin is in progress. Overall more than twenty five percent of headworks has completed.

3. HEADRACE TUNNEL

Excavation of 4021 meter of headrace tunnel is in progress. So far excavation of around

950 meter of HRT has been completed. All the primary support including shotcrete,

rockbolting and forepolling has been done along these excavated length of the Tunnel.

4. HYDRO-MECHANICAL

Contract has been done with Machhapuchhre Metals and Machinery Works Pvt Ltd

(3MW) for the design, fabrication, supply, install and commissioning of Hydro-

Mechanical components

5. ELECTRO-MECHANICAL

Contract has been done with B Fouress Pvt Ltd for the supply, installation and

commissioning of electro-mechanical equipments.

6. TRANSMISSION LINE

The evacuation of the power generated from Lower Modi Khola Hydroelectric Project

needs about 4.5 km of 132 KV transmission line. We have already obtained the survey

license for the route alignment of the transmission line. Detail study of the line is still

ongoing. The New Modi substation, which is the delivery point for evacuating power

generated by the Lower Modi Hydropower Project, and which is to be built by NEA, has

yet to begin construction. NEA has been notified about this and a schedule from NEA in

this regard has been sought. Delay in the construction of the said substation will impact

the commercial operation of this Project.

7. MITIGATION AND ENVIRONMENT

MTL has involved various local employees for the construction works as an

enhancement of local skills. Beside supports for various organization to conduct

awareness program has been done. MTL has provided significant support in

construction and upgrading of local rural roads, water supply and sanitation. MTL is

planning to organize various entrepreneurship trainings and programs to produce skilled

manpower at site.
